IMPROVEMENT IN MARKING-BRUSHES.

Specification forming part of Letters Patent No. 140,228, dated June 24, 1873; application filed Aprilll, 1873.

To all whom it may concern:

Be it known that I, FRANK W. WENT- WORTH, of Boston, in the county of Suffolk and State of Massachusetts, have invented a certain new and useful Marking-Brush, of which the following is a specification The nature of my invention consists in making a marking-brush, the handle of which constitutes a compressible fountain, which is connected by a central tube to the interior of the brush, the object being to furnish a marklug-brush with which the operator may mark and at the same time, with the same hand, cause the ink to flow in just the desired quantity.

Figure 1 is an elevation, showing my invention in full. Fig. 2 is a vertical section of the same. Fig. 3 is an enlarged section of the brush-part.

LetterA represents the brush, which maybe of any desired size and kind. It should be provided with one or more small tubes, like the one represented by D, Figsl, 2, and 3, to facilitate the flow of the contents of the compress- .ible fountain O. E B is a pointed tube, which serves to connect the brush A with the fountain-handleG. O is a fountain, made as shown, and consists of a compressible hollow bulb, made of any suitable material, and of such shape as to form a good handle for the brush. To use this brush, I have simply to compress it and insert the lower end of the tube E into the fluid to be used. By allowing the bulb to expand the fluid is drawn in, and the device is ready for use. While marking, a gentle pressure may be exerted upon the bulb so as to cause the ink to flow in suflicient quantity to supply the brush.

1 claim as my invention In a marking-brush, the combination of-th fountain-handle O with the brush A and interior supply-tube D, all arranged substantially as described, and for the purpose set forth.
